What do you guys think about the new unified shader hardware of shader model 4.0?
Do you think it will be better than the separated pixel/vertex shader nvidia 32/32 and ati 16/48 have right now?
Personally I think a unified cross vector and dot scalar units will be a balance of speed and stability. For example, a unified 64 pipeline can allocate pipeline resource according to the need of the 3d software so frame rate will remain steady and playable.
However, a unified pipeline is slower than a dedicated pipeline design to handle specific pixel/vertex.
The result is slower maximum fill rate in exchange for steady fill rate that never drop below threshhold.
